Instructions for Recording your Presentation for PAM2020


The deadline for video submissions is March 23rd!

Talks will be pre-recorded and submitted as video files to be replayed during the conference. Authors should be available online after their videos are played to answer questions from conference participants.

Please observe the following guidelines when preparing video files of your talks and posters:

  • Duration: 25 minutes for talks, 6 minutes for posters
  • File Format: MPEG-4 (.mp4) file (use the normal H.264 video and AAC audio codecs)
  • Video Size: HD (1280 X 720 or other "720p" setting)
  • Audio Quality: please double check your files before submitting to make sure the audio is clear and audible!


  1. Videos should contain a prominent view of the presentation slides along with audio of the spoken presentation. Optionally videos may contain a shot of the speaker's head for increased engagement. (This shot should be thumbnail-sized and overlayed on the slide images as shown here.) Many presentation softwares allow recording audio and video directly in the application and can export appropriate video files. Please see the notes below for detailed instructions for PowerPoint and KeyNote. If you use a different application, please see the notes under Other Options.
  2. PowerPoint
    1. Follow these instructions to add audio (and optionally video) to your slides.
    2. Follow these instructions to generate an MPEG-4 (.mp4) file from your slides and audio / video.

    Alternatively, you can follow this video tutorial which goes through both of these steps.

    1. Follow these instructions to record a voiceover narration for your slides.
    2. Follow these instructions to export the presentation using QuickTime. Note that recent versions of KeyNote export MPEG-4 files even though they do not show the .mp4 extension.

    Also, see this video tutorial if you like.

    Other Options
    1. Record your screen (and microphone) while giving the presentation. There are effective and free options to do this on Linux, macOS, and Windows.
    2. As a last resort, and only if you are comfortable directly editing video, you can export your slides as images, record an audio track, and combine the two using software like kdenlive, iMovie, or others.
  3. Final videos should be submitted via a downloadable link (using e.g., Dropbox) to by March 23rd. Please name the file with the paper or poster number followed by the presenting author's full name.
